The effect of fines recycling on industrial grinding performance

The product size, % +212 μm, was correlated with the main operating variables such as Bond index, feed tonnage, power consumption and circulating load. The model was adjusted to describe normal operation without fines recycling. Then, the comparison of experimental data with fines recycling and those without it, showed a decrease of 2.5% in % +212 μm, for the same feed capacity tph.
